We see few more details from the top, such as the buttons and the screen on top:

The zoomed in details:

Flat surface next to the EVF integrates a big second screen. It will be an e-display similar as on the D850. On the images above it even looks similar to the Fujifilm X-H1 display which, in my eyes, looks awesome.

The grip again looks big, just as many of us wanted it to be.

The grip goes a bit up from the normal top level behind. Not sure why they did not just level the bsck a bit up to the same level.

Lens looks strange. First I thought there is an adapter with a Sigma Art 24-105mm on it. But it would be strange that they do not use their own lenses. Only imaginable reason would be, that they want ro emphasize, that they will supporr third party lenses in the future. This would be great news, but is not very likely. So the best guess: The Nikon 24-70mm f/4 for the mirrorless.
